Anthurium plant named ‘ANTHOSZMO’

ABSTRACT

A new Anthurium plant named ‘ANTHOSZMO’ particularly distinguished by having shiny, pink, ovate and durable spathes that retain the original color for a very long period of time, pink spadices with orange-light green tips, dark green and deltoid, durable leaves, early and rich flowering continuously throughout the year, and a plant height of 24.0 cm to 29.0 cm is disclosed.

Genus and species: Anthurium andraeanum L.

Variety denomination: ‘ANTHOSZMO’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new and distinct variety of Anthurium, botanically known as Anthurium andraeanum L., and hereinafter referred to by the variety name ‘ANTHOSZMO’. The new Anthurium plant is a product of a planned breeding program conducted by the inventor in Bleiswijk, the Netherlands. The objective of this breeding program was to create a new 24.0 cm to 29.0 cm height plant with shiny, pink, ovate and durable spathes.

The new variety originated from a cross-pollination made in December 2001 in Bleiswijk, The Netherlands. The female parent was a red Anthurium pot plant designated ‘ANTHEPEDI’ (U.S. Plant Pat. No. 18,644), and the male parent was a white Anthurium pot plant designated ‘3644-01’ (unpatented).

Asexual reproduction of the new variety by tissue culture in 2014 in Bleiswijk, The Netherlands, has demonstrated that the new variety reproduces true to type with all of the characteristics, as herein described, firmly fixed and retained through successive generations.

Plant Breeder's Rights for this variety have been applied for in the European Union on Nov. 25, 2016. ‘ANTHOSZMO’ has not been made publicly available or sold anywhere in the world more than one year prior to the effective filing date of this application.

SUMMARY OF THE INVENTION

The following are the most outstanding and distinguishing characteristics of this new variety when grown under normal horticultural practices in Bleiswijk, The Netherlands:

-   -   1) Shiny, pink, ovate spathes;     -   2) Pink spadices with orange-light green tips; and     -   3) Green, deltoid leaves.

DESCRIPTION OF THE PHOTOGRAPHS

This new Anthurium plant is illustrated by the accompanying photographs which show the overall plant habit including blooms and foliage of the plant; the colors shown are as true as can be reasonably obtained by conventional photographic procedures. The photographs are of a 28-week old plant grown in a greenhouse in Bleiswijk, The Netherlands, in October 2018. Colors in the photographs may differ from the color values cited in the detailed botanical description, which accurately describe the actual colors of the new variety.

FIG. 2 shows a close-up of the mature spathe.

FIG. 3 shows a close-up of the upper leaf blade surface.

DESCRIPTION OF THE NEW VARIETY

The following detailed description sets forth the distinctive characteristics of ‘ANTHOSZMO’. The data which define these characteristics were collected from asexual reproductions carried out in Bleiswijk, The Netherlands. The plant history was taken on 28-week old plants which were planted from tissue culture in 9 centimeter (diameter) pots and grown in a glass greenhouse between 19° C. and 24° C. Observations were made in October 2018. Color readings were taken under 5000 lux natural light in the greenhouse. Color references are primarily to The R.H.S. Colour Chart of The Royal Horticultural Society of London (R.H.S.) (2015).

COMPARISON WITH PARENTAL AND SIMILAR COMMERCIAL VARIETIES

‘ANTHOSZMO’ differs from the female parent plant ‘ANTHEPEDI’ (U.S. Plant Pat. No. 18,644) in that ‘ANTHOSZMO’ has spathes that are pink, spadices that are RHS 51D at the base and RHS 152B and 26A at the tip, and cataphylls that are green on the outside, whereas ‘ANTHEPEDI’ has spathes that are red, spadices that are RHS 155B at the base and RHS 153D at the tip, and cataphylls that are light green on the outside with a bit of red at the tip.

‘ANTHOSZMO’ differs from the male parent plant ‘3644-01’ (unpatented) in that ‘ANTHOSZMO’ has spathes that are pink and spadices that are RHS 51D at the base and RHS 152B and 26A at the tip, whereas ‘3644-01’ has spathes that are white and spadices that are RHS 158B at the base and RHS 10C and 150C at the tip.

‘ANTHOSZMO’ differs from similar commercial variety ‘ANTHDINWAQ’ (U.S. Plant Pat. No. 26,048) in that ‘ANTHOSZMO’ has abruptly acuminate spathe apexes and deltoid leaves, whereas ‘ANTHDINWAQ’ has acute spathe apexes and ovate leaves. Additionally, ‘ANTHOSZMO’ has longer spathes than ‘ANTHDINWAQ’.

‘ANTHOSZMO’ differs from similar commercial variety ‘ANTHDATAM’ (U.S. Plant Pat. No. 27,699) in that ‘ANTHOSZMO’ has ovate spathes with abruptly acuminate apexes and deltoid leaves, whereas ‘ANTHDATAM’ has cordate spathes with mucronate apexes and ovate-cordate leaves. 

I claim:
 1. A new and distinct variety of Anthurium plant named ‘ANTHOSZMO’, substantially as illustrated and described herein.
